Note that exact reason why your code is frozen is not because you set too high request.recv() buffer size. Here is explained What means buffer size in socket.recv(buffer_size)
This code will work until it'll receive an empty TCP message (if you'd print this empty message, it'd show b''
):
while True:
data = self.request.recv(1024)
if not data: break
And note, that there is no way to send empty TCP message. socket.send(b'')
simply won't work.
Why? Because empty message is sent only when you type socket.close()
, so your script will loop as long as you won't close your connection.
As Hans L pointed out here are some good methods to end message.
It is simple: if recv()
returns 0 bytes; you will not receive any more data on this connection. Ever. You still might be able to send.
It means that your non-blocking socket have to raise an exception (it might be system-dependent) if no data is available but the connection is still alive (the other end may send).
For streaming protocols such as TCP, you can pretty much set your buffer to any size. That said, common values that are powers of 2 such as 4096 or 8192 are recommended.
If there is more data then what your buffer, it will simply be saved in the kernel for your next call to recv
.
Yes, you can keep growing your buffer. You can do a recv into the middle of the buffer starting at offset idx
, you would do:
recv(socket, recv_buffer + idx, recv_buffer_size - idx, 0);
Putting this before the command seems to work NODE_TLS_REJECT_UNAUTHORIZED=0
.
ex: NODE_TLS_REJECT_UNAUTHORIZED=0 npm ...
It would be best to figure out how to make node see self signed certificate as valid. strict-ssl suggestion above didn't work for me for some reason. If you understand the security implications and need a temporary quick fix, this is what I found in some random github issues during Google search of the error.

You can easily present Html.ActionLink as a button by using the appropriate CSS style. For example:
@Html.ActionLink("Save", "ActionMethod", "Controller", new { @class = "btn btn-primary" })

You can use the datetime
module for working with dates and times in Python. The strftime
method allows you to produce string representation of dates and times with a format you specify.
>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'
Use str(ex) to print execption
try:
#your code
except ex:
print(str(ex))

In addition to the main answer: if you have more than one service on the same server that uses websockets, you might want to do this to separate them, by using a custom path (*):
Node server:
var io = require('socket.io')({ path: '/ws_website1'}).listen(server);
Client HTML:
<script src="/ws_website1/socket.io.js"></script>
...
<script>
var socket = io('', { path: '/ws_website1' });
...
Apache config:
RewriteEngine On
RewriteRule ^/website1(.*)$ http://localhost:3001$1 [P,L]
RewriteCond %{REQUEST_URI} ^/ws_website1 [NC]
RewriteCond %{QUERY_STRING} transport=websocket [NC]
RewriteRule ^(.*)$ ws://localhost:3001$1 [P,L]
RewriteCond %{REQUEST_URI} ^/ws_website1 [NC]
RewriteRule ^(.*)$ http://localhost:3001$1 [P,L]
(*) Note: using the default RewriteCond %{REQUEST_URI} ^/socket.io
would not be specific to a website, and websockets requests would be mixed up between different websites!
You cannot add an arbitrary column to a DataFrame
in Spark. New columns can be created only by using literals (other literal types are described in How to add a constant column in a Spark DataFrame?)
from pyspark.sql.functions import lit
df = sqlContext.createDataFrame(
[(1, "a", 23.0), (3, "B", -23.0)], ("x1", "x2", "x3"))
df_with_x4 = df.withColumn("x4", lit(0))
df_with_x4.show()
## +---+---+-----+---+
## | x1| x2| x3| x4|
## +---+---+-----+---+
## | 1| a| 23.0| 0|
## | 3| B|-23.0| 0|
## +---+---+-----+---+
transforming an existing column:
from pyspark.sql.functions import exp
df_with_x5 = df_with_x4.withColumn("x5", exp("x3"))
df_with_x5.show()
## +---+---+-----+---+--------------------+
## | x1| x2| x3| x4| x5|
## +---+---+-----+---+--------------------+
## | 1| a| 23.0| 0| 9.744803446248903E9|
## | 3| B|-23.0| 0|1.026187963170189...|
## +---+---+-----+---+--------------------+
included using join
:
from pyspark.sql.functions import exp
lookup = sqlContext.createDataFrame([(1, "foo"), (2, "bar")], ("k", "v"))
df_with_x6 = (df_with_x5
.join(lookup, col("x1") == col("k"), "leftouter")
.drop("k")
.withColumnRenamed("v", "x6"))
## +---+---+-----+---+--------------------+----+

## | 3| B|-23.0| 0|1.026187963170189...|null|
## +---+---+-----+---+--------------------+----+
or generated with function / udf:
from pyspark.sql.functions import rand
df_with_x7 = df_with_x6.withColumn("x7", rand())
df_with_x7.show()

Performance-wise, built-in functions (pyspark.sql.functions
), which map to Catalyst expression, are usually preferred over Python user defined functions.
If you want to add content of an arbitrary RDD as a column you can
zipWithIndex
on RDD and convert it to data frameAll of the below is copied directly from @TomOnTime's serverfault answer here:
Show lines that only exist in file a: (i.e. what was deleted from a)
comm -23 a b
Show lines that only exist in file b: (i.e. what was added to b)
comm -13 a b
Show lines that only exist in one file or the other: (but not both)
comm -3 a b | sed 's/^\t//'
(Warning: If file a
has lines that start with TAB, it (the first TAB) will be removed from the output.)
NOTE: Both files need to be sorted for "comm" to work properly. If they aren't already sorted, you should sort them:
sort <a >a.sorted
sort <b >b.sorted
comm -12 a.sorted b.sorted
If the files are extremely long, this may be quite a burden as it requires an extra copy and therefore twice as much disk space.
Edit: note that the command can be written more concisely using process substitution (thanks to @phk for the comment):
comm -12 <(sort < a) <(sort < b)
You can use while loop as well to convert an int to binary. Like this,
import java.util.Scanner;
public class IntegerToBinary
{
public static void main(String[] args)
{
int num;
String str = "";
Scanner sc = new Scanner(System.in);
System.out.print("Please enter the a number : ");
num = sc.nextInt();
while(num > 0)
{
int y = num % 2;
str = y + str;
num = num / 2;
}
System.out.println("The binary conversion is : " + str);
sc.close();
}
}
Source and reference - convert int to binary in java example.
In your specific example you don't need to escape the equals - you only need to escape it if it's part of the key. The properties file format will treat all characters after the first unescaped equals as part of the value.
For your particular case you could also use Array#join
when constructing file path type of string:
string = [ROOT_DIR, project, 'App.config'].join('/')]
This has a pleasant side effect of automatically converting different types to string:
['foo', :bar, 1].join('/')
=>"foo/bar/1"
If you know the sessionID then you can use the following:
SELECT * FROM sys.dm_exec_requests WHERE session_id = 62
Or if you want to narrow it down:
SELECT command, percent_complete, start_time FROM sys.dm_exec_requests WHERE session_id = 62
Unrelated to the question (Mehrdad's answer should get you going), and I hope this isn't taken as nitpicky: classes don't inherit interfaces, they implement them.
.NET does not support multiple-inheritance, so keeping the terms straight can help in communication. A class can inherit from one superclass and can implement as many interfaces as it wishes.
In response to Eric's comment... I had a discussion with another developer about whether or not interfaces "inherit", "implement", "require", or "bring along" interfaces with a declaration like:
public interface ITwo : IOne
The technical answer is that ITwo
does inherit IOne
for a few reasons:
ITwo
implements IOne
is flat wrongITwo
inherits IOne
methods, if MethodOne()
exists on IOne
then it is also accesible from ITwo
. i.e: ((ITwo)someObject).MethodOne())
is valid, even though ITwo
does not explicitly contain a definition for MethodOne()
typeof(IOne).IsAssignableFrom(typeof(ITwo))
returns true
We finally agreed that interfaces support true/full inheritance. The missing inheritance features (such as overrides, abstract/virtual accessors, etc) are missing from interfaces, not from interface inheritance. It still doesn't make the concept simple or clear, but it helps understand what's really going on under the hood in Eric's world :-)

This is a Matlab implementation using the polar form of the Box-Muller transformation:
Function randn_box_muller.m
:
function [values] = randn_box_muller(n, mean, std_dev)
if nargin == 1
mean = 0;
std_dev = 1;
end
r = gaussRandomN(n);
values = r.*std_dev - mean;
end
function [values] = gaussRandomN(n)
[u, v, r] = gaussRandomNValid(n);
c = sqrt(-2*log(r)./r);
values = u.*c;
end
function [u, v, r] = gaussRandomNValid(n)
r = zeros(n, 1);
u = zeros(n, 1);
v = zeros(n, 1);
filter = r==0 | r>=1;
% if outside interval [0,1] start over
while n ~= 0
u(filter) = 2*rand(n, 1)-1;
v(filter) = 2*rand(n, 1)-1;
r(filter) = u(filter).*u(filter) + v(filter).*v(filter);
filter = r==0 | r>=1;
n = size(r(filter),1);
end
end
And invoking histfit(randn_box_muller(10000000),100);
this is the result:
Obviously it is really inefficient compared with the Matlab built-in randn.
Having just struggled with this - I'll explain my situation.
I have my tabs within a bootstrap modal and set the following on load (pre the modal being triggered):
$('#subMenu li:first-child a').tab('show');
Whilst the tab was selected the actual pane wasn't visible. As such you need to add active
class to the pane as well:
$('#profile').addClass('active');
In my case the pane had #profile
(but this could have easily been .pane:first-child
) which then displayed the correct pane.
As of Gradle 2.4, you can use gradle wrapper --gradle-version X.X
to configure a specific version of the Gradle wrapper, without adding any tasks to your build.gradle
file. The next time you use the wrapper, it will download the appropriate Gradle distribution to match.
you can check using php in_array() built in function
<?php
$os = array("Mac", "NT", "Irix", "Linux");
if (in_array("Irix", $os)) {
echo "Got Irix";
}
if (in_array("mac", $os)) {
echo "Got mac";
}
?>
and you can also check using this
<?php
$search_array = array('first' => 1, 'second' => 4);
if (array_key_exists('first', $search_array)) {
echo "The 'first' element is in the array";
}
?>
in_array() is fine if you're only checking but if you need to check that a value exists and return the associated key, array_search is a better option.
$data = array(
0 => 'Key1',
1 => 'Key2'
);
$key = array_search('Key2', $data);
if ($key) {
echo 'Key is ' . $key;
} else {
echo 'Key not found';
}

It's recommended not to use the <Button>
tag. Use the <Input type='Button' onclick='return false;'>

Curent class .dropdown-submenu > .dropdown-menu
have left: 100%;
. So, if you want to open submenu on the left side, override those settings to negative left position. For example left: -95%;
. Now you will get submenu on the left side, and you can tweak other settings to get perfect preview.

EDIT: OP's question and my answer are from august 2012. Meanwhile, Bootstrap changed, so now you have .pull-left class. Back then, my answer was correct. Now you don't have to manually set css, you have that .pull-left class.

While configure could find my Boost installation, CMake could not.
Locate FindBoost.cmake and look for LIBRARY_HINTS to see what sub-packages it is looking for. In my case it wanted the MPI and graph libraries.
# Compute component-specific hints.

list(APPEND _Boost_FIND_LIBRARY_HINTS_FOR_COMPONENT ${libdir})
endif()
endforeach()

apt-cache search ... I installed the dev packages since I was building code, and the dev package drags in all the dependencies. I'm not so sure that a standard Boost install needs Open MPI, but this is OK for now.

sudo apt-get install libboost-graph-parallel-dev
Starting with a context, the root view of the associated activity can be had by
View rootView = ((Activity)_context).Window.DecorView.FindViewById(Android.Resource.Id.Content);
In Raw Android it'd look something like:
View rootView = ((Activity)mContext).getWindow().getDecorView().findViewById(android.R.id.content)
Then simply call the findViewById on this
View v = rootView.findViewById(R.id.your_view_id);
If nothing works, try:
git pull --allow-unrelated-histories <repo> <branch>

There is a bot that echoes your chat id upon starting a conversation.
Just search for @chatid_echo_bot
and tap /start
. It will echo your chat id.
Another option is @getidsbot
which gives you much more information. This bot also gives information about a forwarded message (from user, to user, chad ids, etc) if you forward the message to the bot.

The fundamental difference in most programming languages is that unless the unexpected happens a for
loop will always repeat n
times or until a break statement, (which may be conditional), is met then finish with a while
loop it may repeat 0 times, 1, more or even forever
, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while
loop, (or repeat until
), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).
It is worth noting that in Python a for
or while
statement can have break
, continue
and else
statements where:
break
- terminates the loopcontinue
- moves on to the next time around the loop without executing following code this time aroundelse
- is executed if the loop completed without any break
statements being executed.N.B. In the now unsupported Python 2 range
produced a list of integers but you could use xrange
to use an iterator. In Python 3 range
returns an iterator.
So the answer to your question is 'it all depends on what you are trying to do'!
The solution found here helped us to update master to a previous commit that had already been pushed:
git checkout master
git reset --hard e3f1e37
git push --force origin e3f1e37:master
The key difference from the accepted answer is the commit hash "e3f1e37:" before master in the push command.

Try Uri.IsWellFormedUriString()
:
The string is not correctly escaped.
http://www.example.com/path???/file name
The string is an absolute Uri that represents an implicit file Uri.
c:\\directory\filename
The string is an absolute URI that is missing a slash before the path.
file://c:/directory/filename
The string contains unescaped backslashes even if they are treated as forward slashes.
http:\\host/path/file
The string represents a hierarchical absolute Uri and does not contain "://".
www.example.com/path/file
The parser for the Uri.Scheme indicates that the original string was not well-formed.
The example depends on the scheme of the URI.

You'll normally be returning JSON either because:
A) You are building part / all of your application as a Single Page Application (SPA) and you need your client-side JavaScript to be able to pull in additional data without fully reloading the page.
or
B) You are building an API that third parties will be consuming and you have decided to use JSON to serialize your data.
Or, possibly, you are eating your own dogfood and doing both
In both cases render :json => some_data
will JSON-ify the provided data. The :callback
key in the second example needs a bit more explaining (see below), but it is another variation on the same idea (returning data in a way that JavaScript can easily handle.)
:callback
?JSONP (the second example) is a way of getting around the Same Origin Policy that is part of every browser's built-in security. If you have your API at api.yoursite.com
and you will be serving your application off of services.yoursite.com
your JavaScript will not (by default) be able to make XMLHttpRequest
(XHR - aka ajax) requests from services
to api
. The way people have been sneaking around that limitation (before the Cross-Origin Resource Sharing spec was finalized) is by sending the JSON data over from the server as if it was JavaScript instead of JSON). Thus, rather than sending back:
{"name": "John", "age": 45}
the server instead would send back:
valueOfCallbackHere({"name": "John", "age": 45})
Thus, a client-side JS application could create a script
tag pointing at api.yoursite.com/your/endpoint?name=John
and have the valueOfCallbackHere
function (which would have to be defined in the client-side JS) called with the data from this other origin.)
We know React is SPA. Everything is rendered from the root component by expanding to appropriate HTML from JSX.
So it does not matter where you want to use the images. Best practice is to use an absolute path (with reference to public). Do not worry about relative paths.
In your case, this should work everywhere:

Turning off optimization fixes the problem, but it is unnecessary. A safer alternative is to make it illegal for the compiler to optimize out the store by using the volatile
type qualifier.
// Assuming pageptr is unsigned char * already...
unsigned char *pageptr = ...;
((unsigned char volatile *)pageptr)[0] = pageptr[0];
The volatile
type qualifier instructs the compiler to be strict about memory stores and loads. One purpose of volatile
is to let the compiler know that the memory access has side effects, and therefore must be preserved. In this case, the store has the side effect of causing a page fault, and you want the compiler to preserve the page fault.
This way, the surrounding code can still be optimized, and your code is portable to other compilers which don't understand GCC's #pragma
or __attribute__
syntax.

you need to make county_ID
as index for the right frame:
frame_2.join ( frame_1.set_index( [ 'county_ID' ], verify_integrity=True ),
on=[ 'countyid' ], how='left' )
for your information, in pandas left join breaks when the right frame has non unique values on the joining column. see this bug.
so you need to verify integrity before joining by , verify_integrity=True
Box and Cox (1964) suggested a family of transformations designed to reduce nonnormality of the errors in a linear model. In turns out that in doing this, it often reduces non-linearity as well.
Here is a nice summary of the original work and all the work that's been done since: http://www.ime.usp.br/~abe/lista/pdfm9cJKUmFZp.pdf
You will notice, however, that the log-likelihood function governing the selection of the lambda power transform is dependent on the residual sum of squares of an underlying model (no LaTeX on SO -- see the reference), so no transformation can be applied without a model.
A typical application is as follows:
library(MASS)
# generate some data
set.seed(1)
n <- 100
x <- runif(n, 1, 5)
y <- x^3 + rnorm(n)
# run a linear model
m <- lm(y ~ x)
# run the box-cox transformation
bc <- boxcox(y ~ x)
(lambda <- bc$x[which.max(bc$y)])
[1] 0.4242424
powerTransform <- function(y, lambda1, lambda2 = NULL, method = "boxcox") {
boxcoxTrans <- function(x, lam1, lam2 = NULL) {
# if we set lambda2 to zero, it becomes the one parameter transformation
lam2 <- ifelse(is.null(lam2), 0, lam2)
if (lam1 == 0L) {
log(y + lam2)
} else {
(((y + lam2)^lam1) - 1) / lam1
}
}
switch(method
, boxcox = boxcoxTrans(y, lambda1, lambda2)
, tukey = y^lambda1
)
}
# re-run with transformation
mnew <- lm(powerTransform(y, lambda) ~ x)
# QQ-plot
op <- par(pty = "s", mfrow = c(1, 2))
qqnorm(m$residuals); qqline(m$residuals)
qqnorm(mnew$residuals); qqline(mnew$residuals)
par(op)
As you can see this is no magic bullet -- only some data can be effectively transformed (usually a lambda less than -2 or greater than 2 is a sign you should not be using the method). As with any statistical method, use with caution before implementing.
To use the two parameter Box-Cox transformation, use the geoR
package to find the lambdas:
library("geoR")
bc2 <- boxcoxfit(x, y, lambda2 = TRUE)
lambda1 <- bc2$lambda[1]
lambda2 <- bc2$lambda[2]
EDITS: Conflation of Tukey and Box-Cox implementation as pointed out by @Yui-Shiuan fixed.
here is what I used
.ui-autocomplete { max-height: 200px; overflow-y: auto; overflow-x: hidden;}
The overflow auto so the scroll bar will not show when it's not supposed to.
Just the heads up, there seems to be special CSS class for this called form-horizontal
input-append has another side effect, that it drops font-size to zero
Based on the existing answers and on the documentation of Contains method I would recommend the creation of the following extension which also takes care of the corner cases:
public static class VStringExtensions
{
public static bool Contains(this string source, string toCheck, StringComparison comp)
{
if (toCheck == null)
{
throw new ArgumentNullException(nameof(toCheck));
}
if (source.Equals(string.Empty))
{
return false;
}
if (toCheck.Equals(string.Empty))
{
return true;
}
return source.IndexOf(toCheck, comp) >= 0;
}
}
Here was my solution:

document.getElementById("name").disabled = true;
This the best solution for my applications - hope this helps!
The following can be used to retrieve JSESSIONID:
function getJSessionId(){
var jsId = document.cookie.match(/JSESSIONID=[^;]+/);
if(jsId != null) {
if (jsId instanceof Array)
jsId = jsId[0].substring(11);
else
jsId = jsId.substring(11);
}
return jsId;
}
jbernadas already mentioned the Aho-Corasick-Algorithm in order to reduce complexity.
Here is one way to use it in Python:
Download aho_corasick.py from here
Put it in the same directory as your main Python file and name it aho_corasick.py
Try the alrorithm with the following code:
from aho_corasick import aho_corasick #(string, keywords)
print(aho_corasick(string, ["keyword1", "keyword2"]))
Note that the search is case-sensitive
I have another one. I named my css file: default.css. It wouldn't load. When I tried to view it in the browser it showed an empty page.
I changed the name to default_css.css and it started working.
I executed following on my database side.

mysql> SET @@session.time_zone = '+00:00';
mysql> SELECT @@global.time_zone, @@session.time_zone;

What is a CSS map file?
It is a JSON format file that links the CSS file to its source files, normally, files written in preprocessors (i.e., Less, Sass, Stylus, etc.), this is in order do a live debug to the source files from the web browser.
What is CSS preprocessor? Examples: Sass, Less, Stylus
It is a CSS generator tool that uses programming power to generate CSS robustly and quickly.
If you want a video first frame as a thumbnail, than you can use
Add #t=0.1 to your video source, like below
<video width="320" height="240" controls>
<source src="video.mp4#t=0.1" type="video/mp4">
</video>
NOTE: make sure about your video type(ex: mp4, ogg, webm etc)
The best solution is to set the checked or unchecked state (either from client or server) and to not let the user change it after wards (i.e make it readonly) do the following:
<input type="radio" name="name" onclick="javascript: return false;" />
If you want to close only one port, just run this command.
kill -9 $(lsof -t -i:3000)
The difference between pkill
and kill
is someone process clay. In kill you apply a filter. you just stop the port you want.
The pkill
command closes all node processes.
pkill -9 node
Use pkill to avoid memory leaks that occur occasionally during development. if there is more than one node, it kills them all.
The use of scripts in package.json is also exemplified.
"scripts": {
"server:start": "cd server && yarn start",
"server:restart": "cd server && yarn restart",
"frontend:start": "cd frontend && yarn start",
"frontend:restart": "kill -9 $(lsof -t -i:4200) && yarn start:frontend"
},
"scripts": {
"start": "nodemon --watch 'src/**/*.ts' --ignore 'src/**/*.spec.ts' --exec 'ts-node' src/index.ts",
"restart": "pkill -9 node && start",
"kill": "pkill -9 node"
},
You need to set line-height.
<div style="border: 1px solid red;">
<span style="font-size: 38px; vertical-align:middle; float:left; line-height: 38px">Hejsan</span>
<span style="font-size: 13px; vertical-align:middle; float:right; line-height: 38px">svejsan</span>
<div style="clear: both;"></div>
Here's a working example for Nullable Enum return values:
public static TEnum? ParseOptional<TEnum>(this string value) where TEnum : struct
{
return value == null ? (TEnum?)null : (TEnum) Enum.Parse(typeof(TEnum), value);
}
var pinIcon = new google.maps.MarkerImage(

null, /* size is determined at runtime */
null, /* origin is 0,0 */
null, /* anchor is bottom center of the scaled image */
new google.maps.Size(12, 18)
);
Try "`n"
with double quotes. (not single quotes '`n'
)
For a complete list of escaping characters see:

I am using JSCH since about 2000 and still find it a good library to use. I agree it is not documented well enough but the provided examples seem good enough to understand that is required in several minutes, and user friendly Swing, while this is quite original approach, allows to test the example quickly to make sure it actually works. It is not always true that every good project needs three times more documentation than the amount of code written, and even when such is present, this not always helps to write faster a working prototype of your concept.
You don't need to use the clipboard, you can export directly the whole resultset (not just what you see) to a file :
The export runs in the background, a popup will appear when it's done.
In newer versions of DBeaver you can just :
The export runs in the background, a popup will appear when it's done.
Compared to the previous way of doing exports, this saves you step 1 (executing the query) which can be handy with time/resource intensive queries.
The shortest way, I think, is the following:
import struct
val = 0x11223344
val = struct.unpack("<I", struct.pack(">I", val))[0]
print "%08x" % val
This converts an integer to a byte-swapped integer.
While admittedly a bit obscure, I would say that the most typographically pleasing way of doing this is
for (int i = myArray.Length; i --> 0; )
{
//do something
}
<html>
<head></head>
<body>
<script type="text/javascript"

});
</script>
<ol>
<li>First</li>
<li>Second</li>

When it runs, there are two items in the ordered list that show, First, and Third. The second was hidden.
You may have a table called 'test'

In Firefox the onchange fires only when you tab or else click outside the input field. The same is true of Onblur. The difference is that onblur will fire whether you changed anything in the field or not. It is possible that ENTER will fire one or both of these, but you wouldn't know that if you disable the ENTER in your forms to prevent unexpected submits.
This working fine for me.

In Java, all non-static methods are by default "virtual functions." Only methods marked with the keyword final, which cannot be overridden, along with private methods, which are not inherited, are non-virtual.

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download
Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.
func( "1", "2", default, default, default, default, default, "eight" );
you can use display:flex
to do this : http://codepen.io/anon/pen/yCKuz
html,body {
height:100%;
width:100%;
margin:0;
}
body {
display:flex;
}
form {
margin:auto;/* nice thing of auto margin if display:flex; it center both horizontal and vertical :) */
}
or display:table
http://codepen.io/anon/pen/LACnF/
body, html {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
display:table;
}
body {
display:table-cell;
vertical-align:middle;
}
form {
display:table;/* shrinks to fit content */
margin:auto;
}
Add a level in your appsettings.json :
{
"MySettings": {
"MyArray": [
"str1",
"str2",
"str3"
]
}
}
Create a class representing your section :
public class MySettings
{
public List<string> MyArray {get; set;}
}
In your application startup class, bind your model an inject it in the DI service :
services.Configure<MySettings>(options => Configuration.GetSection("MySettings").Bind(options));
And in your controller, get your configuration data from the DI service :
public class HomeController : Controller
{
private readonly List<string> _myArray;
public HomeController(IOptions<MySettings> mySettings)
{
_myArray = mySettings.Value.MyArray;
}
public IActionResult Index()
{
return Json(_myArray);
}
}
You can also store your entire configuration model in a property in your controller, if you need all the data :
public class HomeController : Controller
{
private readonly MySettings _mySettings;
public HomeController(IOptions<MySettings> mySettings)
{
_mySettings = mySettings.Value;
}
public IActionResult Index()
{
return Json(_mySettings.MyArray);
}
}
The ASP.NET Core's dependency injection service works just like a charm :)
When you copy your project you will also need to delete the original remnant intermediate build (someActivity$4.class) files from the C:...\AndroidStudioProjects(project_name)\app\build\intermediates\classes\release... directories. Otherwise you will almost certainly have build failures for the new project if yo attempt to compile the copied project. Refactoring won't solve this.
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))

example
<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);

After following the steps suggested by previous posters, do the following steps:
You should be good to go now.
The empty string is false as a rule.
Apparently the empty string is not respected as empty in all browsers and the presence of the checked attribute is taken to mean checked. So the entire attribute must either be present or omitted.

Open your Java source code document and navigate to the JTable object you have created inside of your Swing class.
Create a new TableModel object that holds a DatePickerTable. You must create the DatePickerTable with a range of date values in MMDDYYYY format. The first value is the begin date and the last is the end date. In code, this looks like:
TableModel datePicker = new DatePickerTable("01011999","12302000");
Set the display interval in the datePicker object. By default each day is displayed, but you may set a regular interval. To set a 15-day interval between date options, use this code:
datePicker.interval = 15;
Attach your table model into your JTable:
JTable newtable = new JTable (datePicker);
Your Java application now has a drop-down date selection dialog.
Try something like this:
public class test
{
public static void main(String a[])
{
long tmp = 1346524199000;
Date d = new Date(tmp);
System.out.println(d);
}
}
Nope, this is not possible at all. There is no provision for it in the mailto:

The best idea to send a file, but have the client send the E-Mail that I can think of is:

Use the following code:
$imageName = time().'.'.$request->input_img->getClientOriginalExtension();
$request->input_img->move(public_path('fotoupload'), $imageName);
You have to use execute immediate (dynamic sql).

SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'') FROM ' || v_table_name;
end loop;
CLOSE get_tables;
END;

bool to int:
x = (x == 'true') + 0
Now the x contains 1 if x == 'true'
else 0.
Note: x == 'true'
will return bool which then will be typecasted to int having value (1 if bool value is True else 0) when added with 0.
You might need to register this DLL using the 32 bit version of regsvr32.exe
:
c:\windows\syswow64\regsvr32 c:\tempdl\temp12.dll
a[len(a):]
- This gets you the length of a to the end. It selects a range. If you reverse a[:len(a)]
it will get you the beginning to whatever is len(a)
.

If any one want it in Java, Here is my Answer, For this you have to call Another Thread.
In a word - yes.
Actually, many classes in the JDK implement multiple interfaces. E.g., ArrayList
implements List
, RandomAccess
, Cloneable
, and Serializable
.
/appointments?users=1d1,1d2..
is fine. It's pretty much your only sensible option since you can't pass in a body with a GET.
As no one has mentioned, another way to create a String out of a single char:
String s = Character.toString('X');
Returns a String object representing the specified char. The result is a string of length 1 consisting solely of the specified char.
as much as everyone hates tables for layout, they do help with stuff like this, either using explicit table tags or using display:table-cell
<div style="width:300px; display:table">
<label for="MyInput" style="display:table-cell; width:1px">label text</label>
<input type="text" id="MyInput" style="display:table-cell; width:100%" />
</div>
BrenBarn is correct. The error means you tried to do something like None[5]
. In the backtrace, it says self.imageDef=self.values[2]
, which means that your self.values
is None
.
You should go through all the functions that update self.values
and make sure you account for all the corner cases.
I know this thread is years ago and issue was fixed too. But I hope this would helps someone else in future since I've encountered some similar issues while I tried to install Oracle WebLogic 12c and Oracle OFR in which its installer is in .jar
format. For mine case, it was either didn't wrap the JDK directory in quotes or simply typo.
Run Command Prompt
as administrator and execute the command in this format. Double check the sentence if there is typo.
"C:\Program Files\Java\jdk1.xxxxx\bin\java" -jar C:\Users\xxx\Downloads\xxx.jar
If it shows something like JRE 1.xxx is not a valid JDK Java Home
, make sure the System variables for JAVA_HOME
in Environment Variables is pointing to the correct JDK directory. JDK 1.8 or above is recommended (2018).
A useful thread here, you may refer it: Why its showing your JDK c:program files\java\jre7 is not a valid JDK while instaling weblogic server?
This works for me:
window.addEventListener("beforeunload", function(event) {_x000D_
event.returnValue = "You may have unsaved Data";_x000D_
});
_x000D_
Here you can find a good example of how to format Y-Axis value.
Also, you can use scaleLabel : "<%=value%>"
that you mentioned, It basically means that everything between <%=
and %>
tags will be treated as javascript code (i.e you can use if
statments...)
You could use the Reflections Project described here
It's quite complete and easy to use.
Brief description from the above website:
Reflections scans your classpath, indexes the metadata, allows you to query it on runtime and may save and collect that information for many modules within your project.
Example:
Reflections reflections = new Reflections(
new ConfigurationBuilder()
.setUrls(ClasspathHelper.forJavaClassPath())
);
Set<Class<?>> types = reflections.getTypesAnnotatedWith(Scannable.class);
Write property value as a array of strings. Like example given over here https://gun.io/blog/multi-line-strings-in-json/. This will help.
We can always use array of strings for multiline strings like following.
{
"singleLine": "Some singleline String",
"multiline": ["Line one", "line Two", "Line Three"]
}
And we can easily iterate array to display content in multi line fashion.
I tried some of these answers, but they didnt work for me (sorry guys); after some more net searching I found this.
With a little modification to his code I now have this function that will return the point of intersection or if no intersection is found it will return -1,-1.
Public Function intercetion(ByVal ax As Integer, ByVal ay As Integer, ByVal bx As Integer, ByVal by As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal dx As Integer, ByVal dy As Integer) As Point
'// Determines the intersection point of the line segment defined by points A and B
'// with the line segment defined by points C and D.
'//
'// Returns YES if the intersection point was found, and stores that point in X,Y.
'// Returns NO if there is no determinable intersection point, in which case X,Y will
'// be unmodified.
Dim distAB, theCos, theSin, newX, ABpos As Double
'// Fail if either line segment is zero-length.
If ax = bx And ay = by Or cx = dx And cy = dy Then Return New Point(-1, -1)
'// Fail if the segments share an end-point.
If ax = cx And ay = cy Or bx = cx And by = cy Or ax = dx And ay = dy Or bx = dx And by = dy Then Return New Point(-1, -1)
'// (1) Translate the system so that point A is on the origin.
bx -= ax
by -= ay
cx -= ax
cy -= ay
dx -= ax
dy -= ay
'// Discover the length of segment A-B.
distAB = Math.Sqrt(bx * bx + by * by)
'// (2) Rotate the system so that point B is on the positive X axis.
theCos = bx / distAB
theSin = by / distAB
newX = cx * theCos + cy * theSin
cy = cy * theCos - cx * theSin
cx = newX
newX = dx * theCos + dy * theSin
dy = dy * theCos - dx * theSin
dx = newX
'// Fail if segment C-D doesn't cross line A-B.
If cy < 0 And dy < 0 Or cy >= 0 And dy >= 0 Then Return New Point(-1, -1)
'// (3) Discover the position of the intersection point along line A-B.
ABpos = dx + (cx - dx) * dy / (dy - cy)
'// Fail if segment C-D crosses line A-B outside of segment A-B.
If ABpos < 0 Or ABpos > distAB Then Return New Point(-1, -1)
'// (4) Apply the discovered position to line A-B in the original coordinate system.
'*X=Ax+ABpos*theCos
'*Y=Ay+ABpos*theSin
'// Success.
Return New Point(ax + ABpos * theCos, ay + ABpos * theSin)
End Function
This is my solution, for any list object you can use this code for convert to xml layout. KeyFather is your principal tag and KeySon is where start your Forech.
public string BuildXml<T>(ICollection<T> anyObject, string keyFather, string keySon)
{
var settings = new XmlWriterSettings
{
Indent = true
};
PropertyDescriptorCollection props = TypeDescriptor.GetProperties(typeof(T));
StringBuilder builder = new StringBuilder();
using (XmlWriter writer = XmlWriter.Create(builder, settings))
{
writer.WriteStartDocument();
writer.WriteStartElement(keyFather);
foreach (var objeto in anyObject)
{
writer.WriteStartElement(keySon);
foreach (PropertyDescriptor item in props)
{
writer.WriteStartElement(item.DisplayName);
writer.WriteString(props[item.DisplayName].GetValue(objeto).ToString());
writer.WriteEndElement();
}
writer.WriteEndElement();
}
writer.WriteFullEndElement();
writer.WriteEndDocument();
writer.Flush();
return builder.ToString();
}
}
In our case, beside changing ToolsVersion from 14.0 to 15.0 on .csproj projet file, as stated by Dominik Litschauer, we also had to install an updated version of MSBuild, since compilation is being triggered by a Jenkins job. After installing Build Tools for Visual Studio 2019, we had got MsBuild version 16.0 and all new C# features compiled ok.
You can use destructuring to only focus on the part of your interest.
So you can do:
let str = "My cow always gives milk";
let [, result] = str.match(/\bcow\s+(.*?)\s+milk\b/) || [];
console.log(result);
_x000D_
In this way you ignore the first part (the complete match) and only get the capture group's match. The addition of || []
may be interesting if you are not sure there will be a match at all. In that case match
would return null
which cannot be destructured, and so we return []
instead in that case, and then result
will be null
.
The additional \b
ensures the surrounding words "cow" and "milk" are really separate words (e.g. not "milky"). Also \s+
is needed to avoid that the match includes some outer spacing.
for java8 we can simply use removeIf function like this
listValues.removeIf(value -> value.type == "Deleted");
Setting a fixed number of decimal places globally is often a bad idea since it is unlikely that it will be an appropriate number of decimal places for all of your various data that you will display regardless of magnitude. Instead, try this which will give you scientific notation only for large and very small values (and adds a thousands separator unless you omit the ","):
pd.set_option('display.float_format', lambda x: '%,g' % x)
Or to almost completely suppress scientific notation without losing precision, try this:
pd.set_option('display.float_format', str)
I've just had this issue and my problem was that I had null rows in a csv file, that contained the text "null" rather than being an empty.

Why not use a PdfPTable
object for this?
Create a fixed width table and use a float array to set the widths of the columns
PdfPTable table = new PdfPTable(10);
table.HorizontalAlignment = 0;
table.TotalWidth = 500f;
table.LockedWidth = true;
float[] widths = new float[] { 20f, 60f, 60f, 30f, 50f, 80f, 50f, 50f, 50f, 50f };
table.SetWidths(widths);
addCell(table, "SER.\nNO.", 2);
addCell(table, "TYPE OF SHIPPING", 1);
addCell(table, "ORDER NO.", 1);

addCell(table, "DESCRIPTION OF GOODS", 2);
addCell(table, "LINE DOC. RECL DATE", 1);
addCell(table, "CLEARANCE DATE", 2);
addCell(table, "CUSTOM PERMIT NO.", 2);
addCell(table, "DISPATCH DATE", 2);
addCell(table, "AWB/BL NO.", 1);
addCell(table, "COMPLEX NAME", 1);
addCell(table, "G. W. Kgs.", 1);
addCell(table, "DESTINATION", 1);
addCell(table, "OWNER DOC. RECL DATE", 1);

Copying a string can be done two ways either copy the location a = "a" b = a or you can clone which means b wont get affected when a is changed which is done by a = 'a' b = a[:]
scut, a cut-like utility (smarter but slower I made) that can use any perl regex as a breaking token. Breaking on whitespace is the default, but you can also break on multi-char regexes, alternative regexes, etc.
scut -f='6 2 8 7' < input.file > output.file
so the above command would break columns on whitespace and extract the (0-based) cols 6 2 8 7 in that order.
Here's a good tutorial on what crontab is and how to use it on Ubuntu. Your crontab line will look something like this:
00 00 * * * ruby path/to/your/script.rb
(00 00

getClass().getResourcesAsStream()
works fine on Android. Just make sure the file you are trying to open is correctly embedded in your APK (open the APK as ZIP).
Normally on Android you put such files in the assets
directory. So if you put the raw_resources.dat
in the assets
subdirectory of your project, it will end up in the assets
directory in the APK and you can use:
getClass().getResourcesAsStream("/assets/raw_resources.dat");
It is also possible to customize the build process so that the file doesn't land in the assets
directory in the APK.
(This is for posts, not pages - the principle is same. The permalink hook is different by exact use case)
I just had the same issue and created a more convenient way to do that - where you don't have to re-edit your functions.php
all the time, or fiddle around with your server settings on each addition (I do not like both).
TLTR
You can add a filter on the actual WP permalink function you need (for me it was post_link
, because I needed that page alias in an archive/category list), and dynamically read the referenced ID from the alias post itself.
This is ok, because the post is an alias, so you won't need the content anyways.
First step is to open the alias post and put the ID of the referenced post as content (and nothing else):
Next, open your functions.php
and add:
function prefix_filter_post_permalink($url, $post) {
// if the content of the post to get the permalink for is just a number...
if (is_numeric($post->post_content)) {
// instead, return the permalink for the post that has this ID
return get_the_permalink((int)$post->post_content);
}
return $url;
}
add_filter('post_link', 'prefix_filter_post_permalink', 10, 2 );
That's it
Now, each time you need to create an alias post, just put the ID of the referenced post as the content, and you're done.
This will just change the permalink. Title, excerpt and so on will be shown as-is, which is usually desired. More tweaking to your needs is on you, also, the "is it a number" part in the PHP
code is far from ideal, but like this for making the point readable.
Use the gca
("get current axes") helper function:
ax = plt.gca()
Example:
import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()
If you're using Swift 2, now you can only use print() to write something to the output.
Apple has combined both println() and print() functions into one.
Updated to iOS 9
By default, the function terminates the line it prints by adding a line break.
print("Hello Swift")
Terminator
To print a value without a line break after it, pass an empty string as the terminator
print("Hello Swift", terminator: "")
Separator
You now can use separator to concatenate multiple items
print("Hello", "Swift", 2, separator:" ")
Both
Or you could combine using in this way
print("Hello", "Swift", 2, separator:" ", terminator:".")
The time problem has to do with the ID3 headers of the MP3 files, which is something your method isn't taking into account as the entire file is copied.
Do you have a language of choice that you want to use or doesn't it matter? That will affect what libraries are available that support the operations you want.
JFrame SetSize() contains the the Area + Border.
I think you have to set the size of ContentPane
of that
jFrame.getContentPane().setSize(800,400);
So I would advise you to use JPanel embedded in a JFrame and you draw on that JPanel. This would minimize your problem.
JFrame jf = new JFrame();
JPanel jp = new JPanel();
jp.setPreferredSize(new Dimension(400,800));// changed it to preferredSize, Thanks!
jf.getContentPane().add( jp );// adding to content pane will work here. Please read the comment bellow.
jf.pack();
I am reading this from Javadoc
The
JFrame
class is slightly incompatible withFrame
. Like all other JFC/Swing top-level containers, a JFrame contains aJRootPane
as its only child. The content pane provided by the root pane should, as a rule, contain all the non-menu components displayed by theJFrame
. This is different from the AWT Frame case. For example, to add a child to an AWT frame you'd write:
frame.add(child);
However using
JFrame
you need to add the child to theJFrame
's content pane instead:
frame.getContentPane().add(child);
You can use this code:
private void OnClickNavigate(object sender, RoutedEventArgs e)
{
NavigatedWindow navigatesWindow = new NavigatedWindow();
navigatesWindow.ShowDialog();
}
There is another way without using $watch, using angular.copy:
var myApp = angular.module('myApp', []);
myApp.factory('Data', function(){
var service = {
FirstName: '',
setFirstName: function(name) {
// this is the trick to sync the data
// so no need for a $watch function
// call this from anywhere when you need to update FirstName
angular.copy(name, service.FirstName);
}
};
return service;
});
// Step 1 Controller
myApp.controller('FirstCtrl', function( $scope, Data ){
});
// Step 2 Controller
myApp.controller('SecondCtrl', function( $scope, Data ){
$scope.FirstName = Data.FirstName;
});
You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.
The ISO-8601 format for a DATETIME
when using only the date is: YYYYMMDD
(no dashes or antyhing!)
For a DATETIME
with the time portion, it's YYYY-MM-DDTHH:MM:SS
(with dashes, and a T
in the middle to separate date and time portions).
If you want to convert a string to a DATE
for SQL Server 2008 or newer, you can use YYYY-MM-DD
(with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.
So in your case, you should try:
declare @a datetime
declare @b datetime
set @a = '2012-04-06T12:23:45' -- 6th of April, 2012
set @b = '2012-08-06T21:10:12' -- 6th of August, 2012
exec LogProcedure 'AccountLog', N'test', @a, @b
Furthermore - your stored proc has problem, since you're concatenating together datetime
and string into a string, but you're not converting the datetime
to string first, and also, you're forgetting the close quotes in your statement after both dates.
So change this line here to this:
IF @DateFirst <> '' and @DateLast <> ''
SET @FinalSQL = @FinalSQL + ' OR CONVERT(Date, DateLog) >= ''' +
CONVERT(VARCHAR(50), @DateFirst, 126) + -- convert @DateFirst to string for concatenation!
''' AND CONVERT(Date, DateLog) <=''' + -- you need closing quotes after @DateFirst!
CONVERT(VARCHAR(50), @DateLast, 126) + '''' -- convert @DateLast to string and also: closing tags after that missing!
With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.
foreach
uses iterators under the hood anyway. It really is just syntactic sugar.
Consider the following program:
import java.util.List;
import java.util.ArrayList;
public class Whatever {
private final List<Integer> list = new ArrayList<>();
public void main() {
for(Integer i : list) {
}
}
}
Let's compile it with javac Whatever.java
,
And read the disassembled bytecode of main()
, using javap -c Whatever
:
public void main();
Code:
0: aload_0
1: getfield #4 // Field list:Ljava/util/List;
4: invokeinterface #5, 1 // InterfaceMethod java/util/List.iterator:()Ljava/util/Iterator;
9: astore_1
10: aload_1
11: invokeinterface #6, 1 // InterfaceMethod java/util/Iterator.hasNext:()Z
16: ifeq 32
19: aload_1
20: invokeinterface #7, 1 // InterfaceMethod java/util/Iterator.next:()Ljava/lang/Object;
25: checkcast #8 // class java/lang/Integer
28: astore_2
29: goto 10
32: return
We can see that foreach
compiles down to a program which:
List.iterator()
Iterator.hasNext()
: invokes Iterator.next()
and continues loopAs for "why doesn't this useless loop get optimized out of the compiled code? we can see that it doesn't do anything with the list item": well, it's possible for you to code your iterable such that .iterator()
has side-effects, or so that .hasNext()
has side-effects or meaningful consequences.
You could easily imagine that an iterable representing a scrollable query from a database might do something dramatic on .hasNext()
(like contacting the database, or closing a cursor because you've reached the end of the result set).
So, even though we can prove that nothing happens in the loop body… it is more expensive (intractable?) to prove that nothing meaningful/consequential happens when we iterate. The compiler has to leave this empty loop body in the program.
The best we could hope for would be a compiler warning. It's interesting that javac -Xlint:all Whatever.java
does not warn us about this empty loop body. IntelliJ IDEA does though. Admittedly I have configured IntelliJ to use Eclipse Compiler, but that may not be the reason why.
You are using ubuntu 12 (quite old one)
First, Open the /etc/mysql/mysql.conf.d/mysqld.cnf file (/etc/mysql/my.cnf in Ubuntu 14.04 and earlier versions
Under the [mysqld] Locate the Line, bind-address = 127.0.0.1 And change it to, bind-address = 0.0.0.0 or comment it
Then, Restart the Ubuntu MysQL Server
systemctl restart mysql.service
Now Ubuntu Server will allow remote access to the MySQL Server, But still you need to configure MySQL users to allow access from any host.
User must be 'username'@'%'
with all the required grants
To make sure that, MySQL server listens on all interfaces, run the netstat command as follows.
netstat -tulnp | grep mysql
Hope this works !
try
block should be around open. Not around prompt.
while True:

});
google.maps.event.addListener(marker, 'mouseover', function() {

});
google.maps.event.addListener(marker, 'mouseout', function() {

In Opera 9.62, Mozilla 3.0.4, Safari 3.2 (for Windows) it helps, if you put some text or at least a whitespace within the same line as the input field.
<div style="line-height: 60px; height: 60px; border: 1px solid black;">
<input type="text" value="foo" />
</div>

IE 7 ignores every CSS hack I tried. I would recommend using padding for IE only. Should make it easier for you to position it correctly if it only has to work within one specific browser.
I found the solution. The answer is very simple. write the below code in your constructor.
import { Component, OnInit, OnDestroy, Input } from "@angular/core";
// Import this, and write at the top of your .ts file
import { HostListener } from "@angular/core";
@Component({
selector: "app-login",
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit, OnDestroy {
// Declare height and width variables
scrHeight:any;
scrWidth:any;
@HostListener('window:resize', ['$event'])
getScreenSize(event?) {
this.scrHeight = window.innerHeight;
this.scrWidth = window.innerWidth;
console.log(this.scrHeight, this.scrWidth);
}
// Constructor
constructor() {
this.getScreenSize();
}
}
====== Working Code (Another) ======
export class Dashboard {
mobHeight: any;
mobWidth: any;
constructor(private router:Router, private http: Http){
this.mobHeight = (window.screen.height) + "px";
this.mobWidth = (window.screen.width) + "px";
console.log(this.mobHeight);
console.log(this.mobWidth)
}
}
Assuming you have access to STL:
std::string filename("filename.conf");
std::string::size_type idx;
idx = filename.rfind('.');
if(idx != std::string::npos)
{
std::string extension = filename.substr(idx+1);
}
else
{
// No extension found
}
Edit: This is a cross platform solution since you didn't mention the platform. If you're specifically on Windows, you'll want to leverage the Windows specific functions mentioned by others in the thread.
sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename
sudo update-rc.d filename defaults
Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln
).
At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename
) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*
. Updated above code to reflect this.
Also as pointed out in the comments (by Charles Brandt), /filename
must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.
Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts
As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.
According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering
", in which case you have to pass sequence and runlevel configuration through command line arguments.
The equivalent argument set for the above example is
sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .
IBM defines it as:
The portion of a program or segment unit in which a declaration applies. An identifier declared in a routine is known within that routine and within all nested routines. If a nested routine declares an item with the same name, the outer item is not available in the nested routine.
Example 1:
function x() {
/*
Variable 'a' is only available to function 'x' and function 'y'.
In other words the area defined by 'x' is the lexical scope of
variable 'a'
*/
var a = "I am a";
function y() {
console.log( a )
}
y();
}
// outputs 'I am a'
x();
Example 2:
function x() {
var a = "I am a";
function y() {
/*
If a nested routine declares an item with the same name,
the outer item is not available in the nested routine.
*/
var a = 'I am inner a';
console.log( a )
}
y();
}
// outputs 'I am inner a'
x();
The vshost.exe feature was introduced with Visual Studio 2005 (to answer your comment).
The purpose of it is mostly to make debugging launch quicker - basically there's already a process with the framework running, just ready to load your application as soon as you want it to.

It turned out that my problem was that I was using a load balancer to handle the SSL, which then sent it over http to the actual server, which then complained.
Description of a fix is here: http://blog.hackedbrain.com/2006/09/26/how-to-ssl-passthrough-with-wcf-or-transportwithmessagecredential-over-plain-http/
Edit: I fixed my problem, which was slightly different, after talking to microsoft support.
My silverlight app had its endpoint address in code going over https to the load balancer. The load balancer then changed the endpoint address to http and to point to the actual server that it was going to. So on each server's web config I added a listenUri for the endpoint that was http instead of https
<endpoint address="" listenUri="http://[LOAD_BALANCER_ADDRESS]" ... />
Use the BufferedStream class in C# to improve performance. A buffer is a block of bytes in memory used to cache data, thereby reducing the number of calls to the operating system. Buffers improve read and write performance.
See the following for a code example and additional explanation: http://msdn.microsoft.com/en-us/library/system.io.bufferedstream.aspx
You can use sys.exit()
to exit from the middle of the main function.
However, I would recommend not doing any logic there. Instead, put everything in a function, and call that from __main__
- then you can use return as normal.
SELECT ..., CONCAT( 'category_id=', tableOne.category_id) as query2 FROM tableOne
LEFT JOIN tableTwo
ON tableTwo.query = query2
I got this error when stubbing with sinon.
The fix is to use npm package sinon-as-promised when resolving or rejecting promises with stubs.
Instead of ...
sinon.stub(Database, 'connect').returns(Promise.reject( Error('oops') ))
Use ...
require('sinon-as-promised');
sinon.stub(Database, 'connect').rejects(Error('oops'));
There is also a resolves method (note the s on the end).

Java has primitive types, objects and arrays and that's it. No typedefs.
Maybe check Hibernate Validator 4.0, the Reference Implementation of the JSR 303: Bean Validation.
This is an example of an annotated class:
public class Address {
@NotNull
private String line1;
private String line2;
private String zip;
private String state;
@Length(max = 20)
@NotNull
private String country;
@Range(min = -2, max = 50, message = "Floor out of range")
public int floor;
...
}
For an introduction, see Getting started with JSR 303 (Bean Validation) – part 1 and part 2 or the "Getting started" section of the reference guide which is part of the Hibernate Validator distribution.

Keep in mind though that passing arguments on Activator.CreateInstance has a significant performance difference versus parameterless creation.
There are better alternatives for dynamically creating objects using pre compiled lambda. Of course always performance is subjective and it clearly depends on each case if it's worth it or not.

You can use input text with "list" attribute, which refers to the datalist of values.
<input type="text" name="city" list="cityname">_x000D_
<datalist id="cityname">_x000D_
<option value="Boston">_x000D_
<option value="Cambridge">_x000D_
</datalist>
_x000D_
This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist
While zolley's answer is perfectly right for the question, here's a more general solution for any range, plus explanation:
=COUNTIF($A$1:$C$50, INDIRECT(ADDRESS(ROW(), COLUMN(), 4))) > 1
Please note that in this example I will be using the range A1:C50
.
The first parameter ($A$1:$C$50
) should be replaced with the range on which you would like to highlight duplicates!
to highlight duplicates:
Format
> Conditional formatting...
Apply to range
, select the range to which the rule should be applied.Format cells if
, select Custom formula is
on the dropdown.Why does it work?
COUNTIF(range, criterion)
, will compare every cell in range
to the criterion
, which is processed similarly to formulas. If no special operators are provided, it will compare every cell in the range with the given cell, and return the number of cells found to be matching the rule (in this case, the comparison). We are using a fixed range (with $
signs) so that we always view the full range.
The second block, INDIRECT(ADDRESS(ROW(), COLUMN(), 4))
, will return current cell's content. If this was placed inside the cell, docs will have cried about circular dependency, but in this case, the formula is evaluated as if it was in the cell, without changing it.
ROW()
and COLUMN()
will return the row number and column number of the given cell respectively. If no parameter is provided, the current cell will be returned (this is 1-based, for example, B3
will return 3 for ROW()
, and 2 for COLUMN()
).
Then we use: ADDRESS(row, column, [absolute_relative_mode])
to translate the numeric row and column to a cell reference (like B3
. Remember, while we are inside the cell's context, we don't know it's address OR content, and we need the content in order to compare with). The third parameter takes care for the formatting, and 4
returns the formatting INDIRECT()
likes.
INDIRECT()
, will take a cell reference and return its content. In this case, the current cell's content. Then back to the start, COUNTIF()
will test every cell in the range against ours, and return the count.
The last step is making our formula return a boolean, by making it a logical expression: COUNTIF(...) > 1
. The > 1
is used because we know there's at least one cell identical to ours. That's our cell, which is in the range, and thus will be compared to itself. So to indicate a duplicate, we need to find 2 or more cells matching ours.

For those using Sass, I have written a mixin for this purpose:
@mixin addSeparator($element, $separator, $padding) {
#{$element+'+'+$element}:before {
content: $separator;
padding: 0 $padding;
}
}
Example:
@include addSeparator('li', '|', 1em);
Which will give you this:
li+li:before {
content: "|";
padding: 0 1em;
}

Just happened to me, and turned out to be different than all other cases listed here.
I happen to have two virtual servers hosted in the same cluster, each with it own IP address. The host configured one of the servers to be the SQL Server, and the other to be the Web server. However, SQL Server is installed and running on both. The host forgot to mention which of the servers is the SQL and which is the Web, so I just assumed the first is Web, second is SQL.
When I connected to the (what I thought is) SQL Server and tried to connect via SSMS, choosing Windows Authentication, I got the error mentioned in this question. After pulling lots of hairs, I went over all the setting, including SQL Server Network Configuration, Protocols for MSSQLSERVER:
Double clicking the TCP/IP gave me this:
The IP address was of the other virtual server! This finally made me realize I simply confused between the servers, and all worked well on the second server.
var x = 1234567;
x.toString().length;
This process will also work forFloat Number

also.

We had a situation where IE forced us to post as text/plain, so we had to manually parse the parameters using getReader. The servlet was being used for long polling, so when AsyncContext::dispatch was executed after a delay, it was literally reposting the request empty handed.
So I just stored the post in the request when it first appeared by using HttpServletRequest::setAttribute. The getReader method empties the buffer, where getParameter empties the buffer too but stores the parameters automagically.
String input = null;
// we have to store the string, which can only be read one time, because when the
// servlet awakens an AsyncContext, it reposts the request and returns here empty handed
if ((input = (String) request.getAttribute("com.xp.input")) == null) {
StringBuilder buffer = new StringBuilder();
BufferedReader reader = request.getReader();
String line;
while((line = reader.readLine()) != null){
buffer.append(line);
}
// reqBytes = buffer.toString().getBytes();
input = buffer.toString();
request.setAttribute("com.xp.input", input);
}
if (input == null) {
response.setContentType("text/plain");
PrintWriter out = response.getWriter();
out.print("{\"act\":\"fail\",\"msg\":\"invalid\"}");
}
I've had good results with FileServlet, as it supports pretty much all of HTTP (etags, chunking, etc.).
This approach shows how to use a class like django's ModelForm and a template tag like {{ form.as_table }}, but have all the table look like data output, not a form.
The first step was to subclass django's TextInput widget:
from django import forms
from django.utils.safestring import mark_safe
from django.forms.util import flatatt
class PlainText(forms.TextInput):
def render(self, name, value, attrs=None):
if value is None:
value = ''
final_attrs = self.build_attrs(attrs)
return mark_safe(u'<p %s>%s</p>' % (flatatt(final_attrs),value))
Then I subclassed django's ModelForm to swap out the default widgets for readonly versions:
from django.forms import ModelForm
class ReadOnlyModelForm(ModelForm):
def __init__(self,*args,**kwrds):
super(ReadOnlyModelForm,self).__init__(*args,**kwrds)
for field in self.fields:
if isinstance(self.fields[field].widget,forms.TextInput) or \
isinstance(self.fields[field].widget,forms.Textarea):
self.fields[field].widget=PlainText()
elif isinstance(self.fields[field].widget,forms.CheckboxInput):
self.fields[field].widget.attrs['disabled']="disabled"
Those were the only widgets I needed. But it should not be difficult to extend this idea to other widgets.

and all other integer types are implementation defined, C99 only specifies:
5.2.4.2.1 "Sizes of integer types <limits.h>
" gives the minimum sizes:
1 [...] Their implementation-defined values shall be equal or greater in magnitude (absolute value) to those shown [...]
- UCHAR_MAX 255 // 2 8 - 1
- USHRT_MAX 65535 // 2 16 - 1
- UINT_MAX 65535 // 2 16 - 1
- ULONG_MAX 4294967295 // 2 32 - 1
- ULLONG_MAX 18446744073709551615 // 2 64 - 1
6.2.5 "Types" then says:
8 For any two integer types with the same signedness and different integer conversion rank (see 6.3.1.1), the range of values of the type with smaller integer conversion rank is a subrange of the values of the other type.
and 6.3.1.1 "Boolean, characters, and integers" determines the relative conversion ranks:
1 Every integer type has an integer conversion rank defined as follows:
- The rank of long long int shall be greater than the rank of long int, which shall be greater than the rank of int, which shall be greater than the rank of short int, which shall be greater than the rank of signed char.
- The rank of any unsigned integer type shall equal the rank of the corresponding signed integer type, if any.
- For all integer types T1, T2, and T3, if T1 has greater rank than T2 and T2 has greater rank than T3, then T1 has greater rank than T3
To go along with the previous answers, this is how I do it as a one-liner. This is for getting the actual text of the selected option. There are good examples for getting the index number already. (And for the text, I just wanted to show this way)
let selText = document.getElementById('elementId').options[document.getElementById('elementId').selectedIndex].text
In some rare instances you may need to use parentheses, but this would be very rare.
let selText = (document.getElementById('elementId')).options[(document.getElementById('elementId')).selectedIndex].text;
I doubt this processes any faster than the two line version. I simply like to consolidate my code as much as possible.
Unfortunately this still fetches the element twice, which is not ideal. A method that only grabs the element once would be more useful, but I have not figured that out yet, in regards to doing this with one line of code.
Two ways, if you're using PHP5 (or higher)
copy('http://www.google.co.in/intl/en_com/images/srpr/logo1w.png', '/tmp/file.png');
If not, use file_get_contents
//Get the file
$content = file_get_contents("http://www.google.co.in/intl/en_com/images/srpr/logo1w.png");
//Store in the filesystem.
$fp = fopen("/location/to/save/image.png", "w");
fwrite($fp, $content);
fclose($fp);
From this SO post
function getArgs(args) {
var argsObj = {};
var argList = /\(([^)]*)/.exec(args.callee)[1];
var argCnt = 0;
var tokens;
while (tokens = /\s*([^,]+)/g.exec(argList)) {
argsObj[tokens[1]] = args[argCnt++];
}
return argsObj;
}
you can also try
var query = from p in list
where p.Age > 18
select p;
Another option is to change the text color (to light gray for example) for the disabled state.
In the storyboard editor, choose Disabled
from the State Config
popup button. Use the Text Color
popup button to change the text color.
In code, use the -setTitleColor:forState:
message.
If the commit you want to revert is a merged commit (has been merged already), then you should either -m 1
or -m 2
option as shown below. This will let git know which parent commit of the merged commit to use. More details can be found HERE.
git revert <commit> -m 1
git revert <commit> -m 2
Add .idea
and *.iml
to .gitignore
, you don't need those files to successfully import and compile the project.
Use insertAdjacentHTML
if it's available, otherwise use some sort of fallback. insertAdjacentHTML is supported in all current browsers.
div.insertAdjacentHTML( 'beforeend', str );
Live demo: http://jsfiddle.net/euQ5n/
You can try the simple one
select to_date('2020-07-08T15:30:42Z','yyyy-mm-dd"T"hh24:mi:ss"Z"') from dual;
nullptr
is always a pointer type. 0
(aka. C's NULL bridged over into C++) could cause ambiguity in overloaded function resolution, among other things:
f(int);
f(foo *);
Installing postgres using apt-get
does not create a user role or a database.
To create a superuser role and a database for your personal user account:
sudo -u postgres createuser -s $(whoami); createdb $(whoami)
In my case it was enough to exclude only path 'META-INF/DEPENDENCIES' on yourProject/app/build.gradle
inside android{}
. Here it is
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
}
And then do Clean Project and Rebuild Project.
That's probably the C++ runtime library. Since it's a DLL it is not included in your program executable. Your friend can download those libraries from Microsoft.
I do this to post a delayed runnable:
myHandler.postDelayed(myRunnable, SPLASH_DISPLAY_LENGTH);
And this to remove it: myHandler.removeCallbacks(myRunnable);
function setToggleInputsinPnl(pnlName) {
var domCount = pnlName.length;
for (var i = 0; i < domCount; i++) {
if (pnlName[i].type == 'text') {
pnlName[i].value = '';
} else if (pnlName[i].type == 'select-one') {
pnlName[i].value = '';
}
}
}
HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.
Yes and you can do so with formatting rules specified by the currently-imbued locale:
#include <iostream>
#include <iterator>
#include <string>
class timefmt
{
public:
timefmt(std::string fmt)
: format(fmt) { }
friend std::ostream& operator <<(std::ostream &, timefmt const &);
private:
std::string format;
};
std::ostream& operator <<(std::ostream& os, timefmt const& mt)
{
std::ostream::sentry s(os);
if (s)
{
std::time_t t = std::time(0);
std::tm const* tm = std::localtime(&t);
std::ostreambuf_iterator<char> out(os);
std::use_facet<std::time_put<char>>(os.getloc())
.put(out, os, os.fill(),
tm, &mt.format[0], &mt.format[0] + mt.format.size());
}
os.width(0);
return os;
}
int main()
{
std::cout << timefmt("%c");
}
Output:
Fri Sep 6 20:33:31 2013
That should work, I'd put brackets around [Date] as it's a reserved keyword.
I know this is an old question, but as per my recent experience, this happens because the build resources are either deleted or Idea cannot recognize them as the source.
Wherever the error appears, provide sources for the folder/directory and this error must be resolved.
Sometimes even when we assign sources for the whole folder, individual classes might still be unavailable. For novice users simple solution is to import a fresh copy and build the application again to be good to go.
It is advisable to do a clean install after this.
Yes, this is confusing...
According to this blog post, it looks like this is an omission from WPF.
To make it work you need to use a style:
<Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
<Border.Style>
<Style>
<Setter Property="Border.Background" Value="Blue"/>
<Style.Triggers>
<Trigger Property="Border.IsMouseOver" Value="True">
<Setter Property="Border.Background" Value="Green" />
</Trigger>
</Style.Triggers>
</Style>
</Border.Style>
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
</Border>
I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.
This method is in BalusC's StringUtil class. his blog
i use it very often and will trim any string of any value:
/**
* Trim the given string with the given trim value.
* @param string The string to be trimmed.
* @param trim The value to trim the given string off.
* @return The trimmed string.
*/
public static String trim(String string, String trim) {
if (string == null) {
return null;
}
if (trim.length() == 0) {
return string;
}
int start = 0;
int end = string.length();
int length = trim.length();
while (start + length <= end && string.substring(
start, start + length).equals(trim)) {
start += length;
}
while (start + length <= end && string.substring(
end - length, end).equals(trim)) {
end -= length;
}
return string.substring(start, end);
}
ex:
trim("1, 2, 3, ", ", ");
In webforms you could also render almost whole html by hand, except few tags like viewstate, eventvalidation and similar, which can be removed with PageAdapters. Nobody force you to use GridView or some other server side control that has bad html rendering output.
I would say that biggest advantage of MVC is SPEED!
Next is forced separation of concern. But it doesn't forbid you to put whole BL and DAL logic inside Controller/Action! It's just separation of view, which can be done also in webforms (MVP pattern for example). A lot of things that people mentions for mvc can be done in webforms, but with some additional effort.
Main difference is that request comes to controller, not view, and those two layers are separated, not connected via partial class like in webforms (aspx + code behind)
you can also use textbox events -
<input id="txt1" type="text" onchange="SetDefault($(this).val());" onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();">
function SetDefault(Text){
alert(Text);
}
Since the tests will be instantiated like a Spring bean too, you just need to implement the ApplicationContextAware interface:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest implements ApplicationContextAware
{
@Autowired
MyService service;
...
@Override
public void setApplicationContext(ApplicationContext context)
throws BeansException
{
// Do something with the context here
}
}
I added below contents in app "build.gradle"
implementation 'org.apache.poi:poi:4.0.0'
implementation 'org.apache.poi:poi-ooxml:4.0.0'
I had a problem with this kind of sql, I was giving empty list in IN clause(always check the list if it is not empty). Maybe my practice will help somebody.
change the port may help as 80 port is already using somewhere
vi /etc/nginx/sites-available/default
Change the port:
listen 8080 default_server;
listen [::]:8080 default_server;
And then restart the nginx server
nginx -t
service nginx restart
Be careful if you use this value to assign some object's property and call JSON.stringify
later* - nulls will remain, but undefined properties will be omited, as in example below:
var a, b = null;_x000D_
_x000D_
c = {a, b};_x000D_
_x000D_
console.log(c);_x000D_
console.log(JSON.stringify(c)) // a omited
_x000D_
*or some utility function/library that works in similar way or uses JSON.stringify
